.SH NAME
.PP
kubectl autoscale \- Auto\-scale a Deployment, ReplicaSet, or ReplicationController


.SH SYNOPSIS
.PP
\fBkubectl autoscale\fP [OPTIONS]


.SH DESCRIPTION
.PP
Creates an autoscaler that automatically chooses and sets the number of pods that run in a kubernetes cluster.

.PP
Looks up a Deployment, ReplicaSet, or ReplicationController by name and creates an autoscaler that uses the given resource as a reference.
An autoscaler can automatically increase or decrease number of pods deployed within the system as needed.


.SH OPTIONS
.PP
\fB\-\-cpu\-percent\fP=\-1
    The target average CPU utilization (represented as a percent of requested CPU) over all the pods. If it's not specified or negative, the server will apply a default value.

.PP
\fB\-\-dry\-run\fP=false
    If true, only print the object that would be sent, without creating it.

.PP
\fB\-f\fP, \fB\-\-filename\fP=[]
    Filename, directory, or URL to a file identifying the resource to autoscale.

.PP
\fB\-\-generator\fP="horizontalpodautoscaler/v1beta1"
    The name of the API generator to use. Currently there is only 1 generator.

.PP
\fB\-\-include\-extended\-apis\fP=true
    If true, include definitions of new APIs via calls to the API server. [default true]

.PP
\fB\-\-max\fP=\-1
    The upper limit for the number of pods that can be set by the autoscaler. Required.

.PP
\fB\-\-min\fP=\-1
    The lower limit for the number of pods that can be set by the autoscaler. If it's not specified or negative, the server will apply a default value.

.PP
\fB\-\-name\fP=""
    The name for the newly created object. If not specified, the name of the input resource will be used.

.PP
\fB\-\-no\-headers\fP=false
    When using the default output, don't print headers.

.PP
\fB\-o\fP, \fB\-\-output\fP=""
    Output format. One of: json|yaml|wide|name|go\-template=...|go\-template\-file=...|jsonpath=...|jsonpath\-file=... See golang template [
\[la]http://golang.org/pkg/text/template/#pkg-overview\[ra]] and jsonpath template [
\[la]http://releases.k8s.io/HEAD/docs/user-guide/jsonpath.md\[ra]].

.PP
\fB\-\-output\-version\fP=""
    Output the formatted object with the given group version (for ex: 'extensions/v1beta1').

.PP
\fB\-\-record\fP=false
    Record current kubectl command in the resource annotation.

.PP
\fB\-R\fP, \fB\-\-recursive\fP=false
    If true, process directory recursively.

.PP
\fB\-\-save\-config\fP=false
    If true, the configuration of current object will be saved in its annotation. This is useful when you want to perform kubectl apply on this object in the future.

.PP
\fB\-a\fP, \fB\-\-show\-all\fP=false
    When printing, show all resources (default hide terminated pods.)

.PP
\fB\-\-show\-labels\fP=false
    When printing, show all labels as the last column (default hide labels column)

.PP
\fB\-\-sort\-by\fP=""
    If non\-empty, sort list types using this field specification.  The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.

.PP
\fB\-\-template\fP=""
    Template string or path to template file to use when \-o=go\-template, \-o=go\-template\-file. The template format is golang templates [
